Function
ASIC The Converged Network Controller, also known as the intelligent
storage peripheral (ISP) controller, is the heart of the adapter. The
Converged Network Controller is a single integrated ASIC that pro-
vides the processing power that runs the FCoE and NIC protocols.
The Converged Network Controller also interfaces with the PCIe
host bus and controls the I/O operations of the adapter.
Flash 4MB nonvolatile memory, or Flash memory. It contains the boot
code run by the converged network controller when the adapter is
powered up. It contains multiple boot images [the FCode, x86 BIOS,
extensible firmware interface (EFI)] to support a multi-boot capability
on different platforms. It also contains the NVRAM that stores the
per-port adapter configuration parameters, which configure the
adapter during initialization. Adapter configuration parameters
include boot device selection, Fibre Channel connection type (topol-
ogy), frame size, Fibre Channel tape support, and so on.
